Ben*_*tor 3 android android-constraintlayout
如何为 scrollView 设置 maxHeight 属性?我有一个LinearLayout,我以编程方式向这个布局添加了一些视图(行)。当行达到 scrollView 的 maxHeight 时,如何显示滚动?ScrollView 位于 CardView 中
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/textViewTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<androidx.cardview.widget.CardView
android:id="@+id/cardView"
android:layout_width="0dp"
android:layout_height="wrap_content"
app:layout_constrainedHeight="true"
app:layout_constraintBottom_toTopOf="@+id/cardView2"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHeight_max="100dp"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/textViewTitle">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="@+id/linear"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" />
</ScrollView>
</androidx.cardview.widget.CardView>
</androidx.constraintlayout.widget.ConstraintLayout>

因为您正在使用,所以ConstraintLayout您需要向您的CardView
app:layout_constraintTop
app:layout_constraintBotttom

你还需要添加以下几行
app:layout_constrainedHeight="true"
app:layout_constraintHeight_max="300dp" // Change this to your maximum height

它应该看起来像这样
<androidx.cardview.widget.CardView
android:layout_width="0dp"
android:layout_height="wrap_content"
app:cardCornerRadius="@dimen/card_radius_10"
app:layout_constrainedHeight="true"
app:layout_constraintHeight_max="300dp" // Change this to your maximum height
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintBottom_toBottomOf="parent" //Change based on your layout
app:layout_constraintTop_toTopOf="parent"> //Change based on your layout
